Normal Operation
Green LED Indicator
The LED indicator illuminates when the SPD is energized
and operating correctly. Indicator operation: Every
suppression element is connected via logic to the green
LED. Should any suppression element fail, the green LED
will extinguish.
Maintenance
SPDs require minimal maintenance. We recommend
periodic inspection of diagnostic indicators to ensure
proper operation. We also recommend keeping the SPD
clean as appropriate.
Troubleshooting & Service
Please contact us for any service related issues. We want

Temporary Overvoltages (TOVs). In this context, Sustained
Overvoltages may be only a few cycles. Failed SPDs tend
to be symptoms, not root causes. We suggest treating a
failed SPD as a ‘canary in the coalmine’ as there may be
larger issues at play. As a generalization, the single largest
‘killer’ of SPDs is reference to ground issues. If the SPD
